You need to program the wait block for half a second, otherwise it may count the same annotation multiple times. You can test variations of this number for better results (50 was found adecuate for this part as in the image). You need also to add a comparison block, the less than (“_<_“) command from the Operators menu. On the Sensors menu you need to choose the “_ sensor value” block, find the distance sensor on the drop down menu. Under the Control menu you need to choose the forever block, the “wait until _” and the “wait _ secs”. After that, you need to use the “set _ to _” block, choose the variable you created from the drop down menu and add a zero. The first time you enter the menu it will be empty. That needs to be done under the Variables menu (Make a variable and click the checkbox to make it visible on the white canvas). For this, you need to create a new variable called score. You need the start button (“when the flag is clicked”) and a score counter starting from zero.

The programming in Scratch follows the same approach as the WeDo code (a second program alongside the goal keeper code). You need to fill out the numbers 1 and 3 on the empty You need to look for the “pick random _ to _ secs” code under the Operators menu. The motor commands are found under the Motion menu for the motor to turn this way and to turn in reverse. The wait command (“wait _ secs”) is also found over there. We need to look for the start block (“when the flag is clicked” command) and the repeat forever block. Asignamos al motor que gire en una dirección, que espere aleatoriamente un rato (para eso los dados) antes de cambiar de dirección, que vuelva a esperar al azar nuevamente antes de repetir el ciclo una y otra vez más.Ĭoding in Scratch is quite similar. Tenemos que usar el bloque iniciar (triangulo verde) y luego el bloque de repetir para que nuestro portero este moviéndose constantemente.

We need to assign one direction for the motor, then to wait a random time (using the dice), turn the motor the other way, then wait another random time before moving the other way, and to start all over again. We need to use the start button (the play icon) and then the repeat block for the goalie to continue moving like crazy.
